T 0 all to 720m it may concern metal. two like blanksto constitute thesides of the press, subsequently giving the slight bends best adaptingthem for the purpose; employ a. helical spring for separating; the sealelements; provide a closuredoclr for the operating handle whichautomatically releases the same when the press is taken in hand inactuating position and a slight squeeze given thereto, and provide otherimprovements in details of construction.

In the drawings forming' part of this specification, Figure 1. is a sideview of the seal press in its position of use, but showing' theactuating handle locked in place. Fig. 2 is a side sectional view mi:the same. Fig. 3 is anend view thereof. Fig. 1 is a detail view of theplunger. Fig. 5 is a top view of the press.

The main body of the press consists ot two side members 1, 2 preferablyblanked out from sheet metal by the same die, but bent toward each otherat 3 to :torm the handle portion 4:; the jaw section 5 being spaced morewidely. Between these jaw sections 5 are fastened, by riveting orwelding, two blocks 6 and 7. To the block 6 is attached the female diemember 9 by means of a screw 10 descending through the block into a hub8 formed on the member 9. This hub fits snugly in a hole 11 in the blockin order to accurately center it, but at about half the depth of thishole the front end of the block is channeled, as at 12, in order that byreleasing the screw and dropping the member 9 a little, it can then bedrawn torward and away from the block.

The male die member 13 has a pin 14 fixed thereto. which slides freelyin the block 7, the latter being recessed to slidably receive a head 15with which the pin is provided. Between this head and the upperSpecification of Letters Patent.

limit of the recess is a helical spring 16 by which the seal member 13is drawn away from the seal member 9.

The actuating handle 17 is pivoted at 19 below the block 7, and isprovided with a cam surface 20 which, by its engagement with the head 15as the handle is drawn upward, forces the die member 13 intosealingengagement with the die member 9. To keep the die member 13 fromturning; relative to the other die member, the head 15 is given a groove21 which accurately fits the sides oi? the cam 20, as shown in Fig. 8;and to hold the handle 17 from descending below-a desired level, a lip22 is formed close to the cam 20 at a point to meet the head 15 andthereby to hold the handle.

To look the handle in its closed position, a leaf spring 23 is providedat whose outer end is a hook 24 adapted to engage and lock the end ofthe handle. This spring is adapt-- ed normally to retain its hook outor"; reach of the handle-end, but by first dra ing the handle up to itslimit and then pressing the spring toward t1 e same, the hook engagesand locks the handle; but, as soon as the handle is again drawn slightlyupward, the spring throws its hook out of reach of the handle-end andthe latter opens at once.

The spring" 23 is fastened in place by beinggiven a bend 25 slightlymore than a semi-circle in contour, adapted to be sprung upon the pin 26fastened between the members l, the tail 27 thereof resting against astrip 29 by which the upper edges of the portions 4 are inclosed, andthereby holding the hook at the required distance from the handle-end.

The strip 29 is secured in place by eyes 30 at its ends penetrated byrivets 31 passing through the side members 4c, as shown in Fig. 2.

What I claim is:

1. A seal press comprising a body member, a block held thereby having arecess therein, a die member having a hub fitting said recess, and ascrew passing through said block into said hub, the block having achannel to permit the die member to be withdrawn after the screwhasreleased it and its hub is partially removed from the recess.

2. A. seal press comprising a body memher, a block held thereby having ashouldered hole therein, a die member having a headed pinrigidvtherewith slidable in said hole, a helical spring about said pinbetween its head and the shoulder of said hole, and an operating memberhaving a cam surface acting against said head, the latter being slottedto receive said cam surface and to be kept thereby from rotation. 3. Aseal press comprising two separate body sections composed of sheetmetal, two blocks fastened between the same, two die members eachsupported by one of said blocks, an operating handle for pressing one ofsaid die members against the other, and a backing strip for closing, thespace between the upper edges of the handle portion of said bodysections, said strip having an eye at each end, and said handle portionhaving rivets passing through said eyes.

4. A seal press comprising a body portion, die members carried thereby,a pivoted operating handle for actuating one of the die members, aresilient engaging device carried by the bod portion normally out ofreach, of the handle but yieldingly pressable into engagement therewith,whereby a pressure of the handle toward the body portion releases itfrom the engaging device.

5. A seal press comprising a body portion, die members carried thereby,a pivoted operating handle for actuating one of the die members, and ahooked member carried by the body portion normally out of reach of theend of said handle but yieldingly pl'essable into engagement with. saidend, whereby a slight movement of said handle toward the body portionreleases it from said hook.

6. A seal press comprising two spaced body members, die members carriedthereby, an operating handle pivoted between said body members foractuating one of thc die members, resilient means pressing the diemembers apart and swinirii'ig the handle downward, and a hooked springheld be tween said body members having its hook normally out of reach ofthe end of said handle but capable of being pressed into engagement withsaid end.

In testimony that I claim the foregoing invention, I have hereunto setmy hand this 5th day of August, 1921.

HAROLD HELLBERG.
